Lifespan/Longevity

The age of great white sharks can be determined by counting the rings that form on the vertebra. It is believed that great white sharks breed between the ages of 9 and 23 years old and that their lifespan is approximately 30 years (Levine, 1998). Various research indicates that great white sharks live somewhere between 30 and 40 years (Shark Information, 2009).
